![]() but after running the simulations, I noticed the resistor I used to eliminate crossover distortion (R5), was actually making the FETs useless since it was too low of a value I bumped it to 1k since the 25mA target goal is right on the limit of what the op amp can do, which is why I need the boosting stage to begin with. ![]() However finding high voltage BJTs was very difficult and only 1 or 2 parts came up which were any good for the job! I tried using fets which at first seemed like a great idea since I could find tons of them for high voltage applications with suitable SOA, etc. Hi all, I made a thread previously regarding high voltage safety and design considerations here: all in all, I relieved a lot of good feedback regarding the design and since there were no major issues, I decided to stick with the class B output amplifier. ![]()
